Relating the integrated density of states to spectral flow in aperiodic chains.

Johannes Kellendonk (Lyon)

Abstract: Aperiodic insulators have typically richer topological invariants than periodic ones. 

In particular the gap labelling group has more generators. We ask, how we can “measure” the gap labels...

Capillary Hypersurfaces and Variational Methods

Yujie Wu (Stanford)

Firstly, we apply the method of generalized soap bubbles (µ-bubbles) to study manifolds with positive scalar curvature; we prove a rigidity result for free boundary minimal hypersurfaces in a...

Causal inference: A very short intro

Jakob Runge, University of Potsdam

Machine learning excels in learning associations and patterns from data and is increasingly adopted in natural-, life- and social sciences, as well as engineering. However, many relevant research...

Heat and resolvent expansions in the noncommutative case

Matthias Lesch (Bonn)

Heat and resolvent expansions are a fundamental tool in spectral geometry and index theory. In the noncommutative world (á la Connes) such expansions exhibit fundamentally new structures. I will...
